What can the vast majority of elements in the periodic table be classified?

I may need a bit more information to answer your question, but try these out:
 
The vast majority of elements in the periodic table are metals, meaning they have some degree of ductility and malleability, if you are being asked about physical properties.

The vast majority of elements in the periodic table are also solids at room temperature, if you are being asked about phase.

Idont know. if you want an answer you need to give us some context dude.
